Possibility of Time Travel
...e with a few kilometers length. That means, passing through a wormhole is equal to a travel many times faster than light. Yet, wormholes in hyperspace are not open for a long time. Also, we can do our wormholes but they are in atomic sizes. If we were able to widen our wormholes, we would time travel like going to a bookstore down the street. Actually, when we think of time travel, lots of paradoxes occur.

Then how he had born and gone past? And if he weren’t born, he couldn’t have killed his grandmother.

Jim meets a beautiful teenage girl, and then accidentally gets her pregnant with a baby girl. Out of guilt...
